Application August 15, 1949, Serial'No. 110,300I 2 Claims. (01 sis-[40 I a simplified mop-board structure having the iabove, characteristics which can be manufactured at a very reasonablecost, and which can be conveniently installed.

With these'and'other objects in view, my invention consists in theconstruction, arrange- I ment, and combination of the various parts ofmy device, whereby the objects contemplated are attained, as hereinaftermore fully set forth, pointed out in my claims, and illustrated in theaccompanying drawings, in which:

Figure 1 is a forward elevation of the mopboard of my invention,

Figure 2 is a sectional view of Figure 1 taken substantially along theline 22 thereof,

Figure 3 is a schematic plan view of a heating circuit employing my typeof mop-board,

Figure 4 is a modification, and

Figure 5 is an elevation of one of the plugs which can be used in myarrangement.

My invention contemplates the provision of a simple hollow mop-boardstructure, with said mop-board structure including a plurality ofopenings whereby warm air forced into said mop-board will be emittedinto a room or other.

structure and whereby said openings can also serve to function as a coldair return.

I have used the character [0 to designate the forward wall of themop-board, this wall Ill being preferably made of thin sheet metal, the

angular portion l9, the portion l9 merging with the portion l0.

By virtue of this structure it will be noted that the flange II can besecured to the floor 20. and the flange M to the vertical risers 2|.Also, the'usual half-rounds which form the lower trim and which areindicated by the character 22 can be secured against the flange H. Theportion I! includes a series of equally spaced circular openings 23,these openings thereby being directed downwardly, it being understoodhowever that other angles of inclination can be employed. The character24 designates the plaster covering and the character 25'the lath.

The wall I 3 includes a rectangular opening 25 which communicates to afeeder pipe 21, the pipe 21 passing to anytype offorced warm air unit. v

It will now be noted that the mop-board is hollow throughout, and thatany warm air forced upwardly in the direction of the arrow 28 will passinto this mop -board,- and thence .downwardly through the openings 23which warm air impinges on the surface I9 and then is deflectedlaterally in the direction of the arrow 29. The top wall 30 of thefeeder pipe is positioned slightly beneath the openings 23 so that thepressure can be equalized within the mop-board before the air isdischarged too rapidly, thereby providing a uniform flow.

The mop-board by virtue of this construction, provides all of thefunctions of a mopboard and yet provides an eflicient warm aircirculating system, and it will be further noted that the openings willnot normally be at all visible to the eye thereby insuring an attractiveappearance to the mop-board, the dotted line 3| illustrating the angleof visibility. The openings will not be visible above this line usually,and the mop-board will perform its heating function with the openingsbeing practically invisible.

The mop-boards can be made of any desired length consistent with thesize of the room or other structure, and any number of feeder pipes canbe employed. Figure 3 illustrates an installation whereby the mop-boardis shown about a room with the character 32 indicating cold air pipes,and with the mop-boards being blocked at 33. In this form of structurethe warm air will pass in the direction of the arrows 34 and the coldair will return in the direction of the arrows 35, the arrangementthereby providing the completed circulation.

It should be understood that this type of mop-board can be built in avariety of shapes, Figure 4 illustrating a modification wherein themop-board includes the curved portion 36 with the further charactersindicating similar portions as indicated in the other figures, this typenaturally embodying the same principles.

In some cases it may be desirable to block ofl some of the heat emittingopenings, such as behind certain articles of furniture which it isdesired to protect from the heat, in which case I provide the circularplug members 31 which extends into the spring urged prongs 38, theprongs permitting the plugs to be inserted and retained in any number ofopenings to thereby block off openings wherever desired. The mopboardscan be painted or colored any desired color to present an attractiveappearance.

It willInow be noted that my type of mopboard structure provides auniform flow ofwarm air, which flow is well balanced in that the flow isdirected inwardly at all points about the room, and it will be alsonoted that a variety of other advantages are readily apparent.

Some changes may be made in the construction and arrangement of theparts of my invention without departing from the real spirit and purposeof my invention, and it is my intention to cover by my claims anymodified forms of structure or use of mechanical equivalents which maybe reasonably included within their scope.

- I claim as'my invention:

1.- A hot air circulating-device comprising a hollow mop board having aforward wall, a rear wall parallel to and spaced from said forward wall,and upper and lower end walls, said forward wall having 'a downwardlyand inwardly inclined portion having a plurality of laterally spacedopenings, a further outwardly inclined portion extending downwardly andangularly irom said portion, means for admitting warm air-'i'ntosaid-mopboard, the inclination of said openings providing means for directingwarm airdownwardly' from said op'enings'to impinge against said-furtherinclined portion, and where- 4 by said warm air will then be directedlaterally. 2. A hot air circulating device comprising a hollow mop boardhaving a forward wall, a rear wall parallel to and spaced from saidforward wall, and upper and lower end walls, said forward wall having adownwardly and inwardly ,inclined portion having a plurality oflaterally spaced openings, a further outwardly inclined portionextending downwardly and angularly from said portion, means foradmitting warm air into said mop board, the inclination of said openingsproviding means for directing warm air downwardly from said openings toimpinge against said further inclined portion, and whereby said warm airwill then be directed laterally,

said warm air admitting means including a plurality of feeder pipes, thetops of said feeder pipes being positioned beneath said openings toprovide uniform pressures to be built up in said mop board beforeinjection of said warm air.
